PIN INSERTER AND REMOVER FOR FORD VALVES.

Application filed March 27, 1922. Serial No. 547,287.

To all whom it may concern Be it known that I, CLARENCE Cr. BALOOM, a citizen of the United States, residing at Noroton Heights, in the county of Fairfield and State of Connecticut, have invented new and useful Improvements in Pin Inserters and Removers for Ford Valves, of which the following is a specification.

Owing to the construction of the motor in the well known small type of automobiles known as the Ford and the employment of the tool for compressing, the spring, and known as the valve lifter, a very limited space is afforded in which to operate to remove and replace the pin that holds the spring on the valve stem, and it is the object of this invention to produce a tool whereby the pin may be inserted or removed in an easy and expeditious manner, and thus eliminate the present existing difliculties in the insertion and removal of such pins.

The drawings, accompanying and forming part of this specification, illustrate a satisfactory embodiment reduced to practice, and wherein Figure 1 is a perspective view of the improvement.

Figure 2 is a view showing the manner in which the pin is gripped by the improvement for the removal thereof from the stem.

Figure 3 is a similar view showing the manner in which the pin is inserted in the stem, the dotted lines showing the position of the tool after the insertion of the pin.

A valve employed on the engine of Ford automobiles is indicated by the numeral 1, the stem therefor by the numeral 2, and the pin which is inserted in a hole transversely of the stem adj aoent to the outer end thereof, indicated by the numeral 3.

My improved tool comprises a shank 3 that has one of its ends rounded upon itself to form a handle 4, while on its other end there is secured a ferrule 5. At the end of the ferrule there are oppositely curved coacting spring jaws 6 and 7 respectively. The jaws are formed from a single piece of spring metal which is rounded upon itself,

as at 8 and the inner end of the said rounded portion is provided with a barrel or stem 9 that is disposed over the outer end of the shank 3 and is compressed against the said end by the ferrule 5. From the rounded portions 8 the jaws are bent inwardly and from thence rounded outwardly, as at 9, and from thence inwardly, as at 10, the said inwardly rounded portions being then rounded outwardly as at 11 so that a flared mouth is provided between the jaws. The rounded portions 9 of the jaws are designed to receive therebetween the pin 3.

In Figure 2 of the drawings, I have illustrated the manner in which the tool is positioned to cause the jaws to grip the pin therebetween. By reference to this figure, it will be seen that the flared mouth between the jaws is first arranged above the pin and then the tool is moved bodily to grip a projecting end of the pin between the jaws. The tool is then given an outward and downward movement towholly remove the pin from the valve stem.

In Figure 3, I have illustrated the manner in which the pin is reinserted in the valve stem. By reference to this figure, it will be seen that the tool is reversely positioned, that is the jaws have their flared mouth directed toward the valve proper, so that when pressure upon the spring is relieved the same may assist in removing the tool from the pin, but it is not at all necessary that such pressure be exerted upon the device, as a mere downward pressure by the operator on the tool will bring the jaws out of engagement with the pin.

It is thought that the foregoing description, when taken in connection with the drawings willfully set forth the construction, operation and advantages of the improvement and that further detailed description will not be required.

Having described the invention, I claim In a device for the purpose set forth, a shank, a ferrule on one end thereof and coacting spring jaws at the outer end of the ferrule, said jaws being integrally formed from a strip of spring material centrally rounded upon itself and provided with an extension that embraces the end of the shank and that is compressed thereagainst by the ferrule, said jaws being centrally rounded outwardly and from thence inwardly and again outwardly to provide a flared mouth therebetween.

In testimony whereof I affix my signature.
